Application filed May 5, 1915, Serial No. 28,815.

lb all whom it may concern Be it known that I, Nuns-or: L. lvioiiar, acitizen of the United States, residing at ii alden, in the county ofOrange and Eltate of New York, have invented certain new and usefulImprovements in Sanitary Drinkingiubes, of which the following is aspecifica tion.

This invention relates to improvements in individual drinking tubes, andhas for one of its objects to provide a simply constructed device,whereby a person can drink from a receptacle of any size or form, orfrom water flowing through a faucet or from a stream, and at the sametime have the water filtered or rendered free from contamination.

Another object of the invention is to provide a simply constructeddevice of this character, wherein a filtering or disinfecting member mayends of the device and readily rei iovable for renewal or cleansing.

llith these and other objects in view, the invention consists in certainnovel features of construction as hereinafter shown and described, andthen specifically pointed out in the claims; and in the drawingsillustrative of the preferred em odiment of the invention. Figure 1 is alongitudinal elevation in section through the narrow axis. Fig. 2 is alongitudinal elevation in section through the wider axis. Fig. 3 is atransverse section on the line 83 of Fig. 2. Fig. & is a side elevationviewed from one of narrow faces. Fig. 5 is a side elevation viewed fromone of wider faces. Fig. 6 is a sectional detail illustrating a slightmodification in the construction.

Corresponding and to in the following description and like parts arereferred indicated in all the views of the accompanying drawings by thesame reference characters.

The improved device comprises two coacting tubular members 10-11preferably of fiat elliptical form transversely, the outer end of thesection 10 being preferably slightly enlarged and then converged, asrepresented at 12, to form a mouth piece and the section 11 beinglikewise slightly converged and curved laterally, as represented at 13.The member 11 is reduced at one end and provided with a stop shoulder lito receive the inner end of the section 10. The reduced portion of themember 11 is formed with an annular seat 15 at its outer end and thememspecification of Letters Patent.

her 10 is provided with an inwardly directed rib 16 spaced from itsouter end. The reduced portion 15 provides an annular supnort for acup-shaped diaphragm of screen material 17, the dia hragm being turnedin or nangeo at its edges to engage by the Wveen th adjacent inner wallof the I nd the reduced portion 15 of the member 11. By this means, themember 17 is firmly supported in position, and all danger ofdisplacement obviated. By this simple means, an efficient and completeimplement is produced whereby a person can drink'from a glass, cup, orother vessel without contamination, the water being strained through themember 17 before it passes to the mouth of the user. By curving thelower or intake end of the member 11 laterally, as shown in Figs. 1 and1, the implement may be readily employed in running water, such as theflow through a faucet or the like.

in Fig. 6 a slightly modified form of the upport for the cleansingelement is shown,

onsis lng in a cup-like member 18 open at he lower side and arovidedwith a diaihragm of screen material, represented at at the upper side,the open side of the upport bearing upon the screen17. The nember 18-19thus provides means for sup- )orting a body of disinfecting material, indicated at 20, within the receiver 18 and between the screen members17-19. This form of the device may be employed if required.

Having thus described the invention, what is claimed as new is:

1. A device of the class described comprising coacting tubular memberstelescopically united at their confronting ends, one of said membershaving an. annular seat at its inner end and the other member having aninwardly directed stop rib, and a foraminous member having a flangeengaging in the seat and held in position by the stop rib.

2. A device of the class described comprising coacting tubular members,one of said members reduced at one end to telescopically engage theother member and with an annular seat in the reduced portion and theother member having an inwardly directed stop rib, and a filter memberhaving a flange engaging in said seat and held in position by the stoprib.

3. A device of the class described comprising coacting tubular memberstelescopically united at their confronting ends, one of said memberscurving laterally and converging at one end and having an annular seatat Copies of this 'patent maybe obtained for five cents each, by addressin Washington, D.

member having an inwardly directed stop rib, a foraminous member havinga flange 15 engaging said seat, and a receptacle for a disinfectanthaving a foraminous Wall and bearing against said flanged foraminousmember and engaged by said stop rib.

In testimony whereof I affix my signature 20 in presence of twoWitnesses.
